1880 Queen of Thailand drowned because her servants couldn't touch her

The queen and her daughter drowned when the royal boat capsized while on the way to the Bang Pa-In Royal Palace (Summer palace). Despite the presence of many onlookers, they were forbidden on pain of death to touch the queen – not even to save her life.[1] The grief-stricken Chulalongkorn later erected a memorial to her and his unborn child at the Bang Pa-In Palace.
